To all whom it may concern: Y

Be it known that I, EUGENE R. .EAGAN,

citizen of the United States, residing at Hubbard, in the county of.Hardin and State of Iowa, have invented certain new.v

and useful Improvements k,in Soil y Pulverizers, of which the followingis aspecification.

This invention has relation'to soil pulverizers adapted to be applied tobreaking plows, and has for its object to provide a rotary soil engagingmember which: is op erated from one of the supportingywheels of the plowfor the purpose of operating upon the upturned side of the furrow sliceVat the time that the said slice is being turned.

With this object in view, the attachment lincludes a bar adapted to be vapplied to ythe beam of a breaking plow and upo'n which is pivotallymounted arms. Meansis provided for resiliently holding the free endportions of said arms in ylowered positions, and a soil engaging memberis journaled at: the free end portions of the arms and is located justbeyond the outer surface of the moldboard,

of the plow bottom.y Means is provided for rotating the said soilengaging member from the landside wheel of the plow structure;

For a full understanding of the invention. reference is to be hadto thefollowing Jdescription and accompanying drawings, in which:

Figure 1 is a perspective view of the'pull verizer attached to a plow.;andlFig. 2 is an end view of the soil engaging member of the pulverizertCorresponding and like parts are referred to in the followingdescription and indicated in all the views of the accompanying drawfings by the same'reference characters. .f Y

The plow to which the attachment 4,is

adapted to be applied is of the usualV sulky type and includes a beamwlto which it attached a landside wheel 2 and which carries a bottom 3having the usual moldboard 4. The attachment includes abar l5 which isclamped or otherwise secured to the beam 1 at the rear down-turned por-ktion thereof and which is sustained in its position by means of bracesand 7 Arms 8 and 9 are pivoted to the ends of the bar 5, the arm 9 beingat' lthe rear end of the' said bar, and the'arm 8 at the front end, thearm 9 being longer than the arm 8. A brace rod 1() connects theintermediate portions of the arms 8 and 9 together, andbrackets 11 areymounted upon the beam 1 and carry slotted bars 12 which receive. theinterme fdiate portions ofthe said rod 10. The l.bars i '12 areadjustably mounted "with :relationlv to the brackets 11, and, as shown,the means for adjustment consistsof nuts 13 which are screw threadedupon theuppe'r ends of the.

said bars and which bear against the upper surfaces of the brackets '111Normally the rod 10 rests at the lower ends of the slots `in the bars12. A spring 14 is connected at one end with the rod 10 and at, itsother lend `with the beam 1,' and is under rtension with a tendency tohold the rod 10"*in the lower.. ends of the slots provided 'in the bars12. ["A weaker spring 15 is connected at its lower end withthe rod 10and at its upper end with the bar 5, and serves as means for ypreventingthe` rod 1Q from moving downwardly too suddenly and jarring theattachment-by coming in `forcible contact with the lower ends of theslots provided in the bars 12. i A shaft 16 is journaled for rotation atthe outer or free ends of the arms 8 and 9 and the said shaft in thevicinity of its ends carries spiders 17; rThe peripheries` of thespiders 17 are connectedl j' together byr hol- :low .spaced bars 18 uponwhich are .mounted n soiliengaging blades 19. A bevel pinion :2O 1'35 lis `fixed to the-rear end of theshaft 16, and Vaishaft 21 is journaledinarms 22 which are suitably supported from the plow beam or parts'ojr"the structurev of the attachment, and thesaidshaft 21 atits yrear endcarries a beveled pinion 23 which meshes with the pinion o20. rlhe soilpulveriz'ing member of which the parts 17, 1S and 19 areI components islo-V" i cated just one side of the moldboard 4 of the plowbottom 3 andis adapted' to operate upon the 'upturned side of the furrow slice asthe said slice is being turned by the said" moldboard. A gear wheel 24.is Xed to the' spokes ofthe landside'wheel 2 by means'of ioo clamps 25,andthe-shaft 21 provided withv va pinion 26 which" meshes with the gear'wheel 24.v Therefore it will bevseeny thatV as .thecplowjbottom .3 isturning a furrow slice,

the ,landside l'wheel is. rotating and rotaryv movement is transmittedthrough the interlmeshing gear wheel 24 andpinionA 25 to the? shaft 21.yFrom the shaft y2,1 this movement is transmitted j through theintermeshing pinions 2O and 23 to thesha'ft 16 which in turnrotatesfthev bars 18 .and soil engaging members 19 about its axis, thesaid members 19 come in contact with the upturned side of the furrowslice the said slice is efllectually pulverized at the time that it isbeing turned, which leaves the `soil in good condition for subsequentrolling preparatory to planting.

Having thus described the invention, what is claimed as new is 1. Apulverizer attachment for a plow including a beam and landside wheel,comprising a bar adapted to be applied to the plow beam, arms pivotallymounted upon the bar, means adapted to be carried by the plow beam forlimiting the downward movement of the arms, resilient means for holdingthe arms in lowermost position, a soil engaging member j ournaled uponthe arms, and means for rotating the said soil engaging member from thelandside wheel of the plow.

2. A pulverizer attachment for a plow including a beam and landsidewheel, comprising a bar adapted to be applied to the plow beam, armspivotally mounted upon the bar and rigidly connected together, meansadapted to be carried by the plow beam for limiting the downwardswinging movement of the arms, resilient means for holding the arms inlowermost positions, a soil engaging member journaled for rotationbetween the arms, and means for rotating said member from the landsidewheel of the plow.

3. A pulverizer attachment for a plow including a beam and landsidewheel, comprising a bar adapted to be applied to the plow beam, armspivoted to the bar, means rigidly connecting the arms together, bracketsadapted to be applied to the plow beam, bars 'adjustably mounted in thebrackets and havingslots which receive the connecting means between thepivoted arms and which limit the downward swinging movement of the arms,resilient means for holding the arms in lowermost positions, a soilengaging member journaled between the arms, and means for rotating thesoil engaging member from the landside wheel of the plow.

et. A pulverizer attachment for a plow including a beam and landsidewheel, comprising a bar adapted to be applied to the plow beam, armspivoted to the bar, means for limiting the downward swinging movement ofthe arms, resilient means for holding the arms in lowermost positions, ashaft journaled in the arms, means for rotating the shaft from thelandside wheel of the plow, spiders mounted upon the shaft, spaced barsconnecting said spiders together, and soil engaging members mounted uponthe said spaced bars.

In testimony whereof, I aiix my signature in presence of two witnesses.
